General Description

The MSC1209 is a Bi-CMOS display driver for a 1/2-duty vacuum fluorescent display tube.

The MSC1209 consists of an 84-bit shift register, an 84-bit latch circuit, a 10-bit digital dimming circuit, 42-bit segment drivers, a 2-bit grid circuit, and a cascade control circuit.

The MSC1209 is interfaced with a microcontroller by using three signal lines of LOAD, CLOCK, and DATA.

Key Features

  • Power supply voltage: 8V to 18V (Built-in 5V regulator for logic).
  • Operating temperature range:.
  • 40 to +105°C.
  • Driving 42 segments directly: VOH=VDD.
  • 0.5V at IOH=.
  • 3.0mA (VDD=15.0V).
  • Built-in digital dimming circuit 10-bit resolution Programmable in the duty range of 0/2048 (0%) to 1016.5/2048 (49.6%).
  • 3 interfaces with microcontroller: LOAD, CLOCK, DATA.
  • Cascade connection available (The cascaded MSC1209 ICs can share.
